The best you can do for an English dub is the Australian DVDs. It's the same dub and editing as the US version, but at least you get the full picture. Still waiting on the second half to be released though.
The US version also has 3:2 pulldown, whereas the Australian version is progressive 25fps and seems to have slightly betting picture quality (probably helped having 4 episodes per disc rather than 10).
If you want the original cut, the best is probably the Korean DVDs. Widescreen, with Japanese audio and English subtitles.
What was the medium for your TV reception, Cable, or broadcast? If Cable, was it digital? I just cannot see why the 4.5 MHz bandwidth of the TV signal would make the picture so dull, nor can I fathom why they would dull it deliberately. It is just so great a difference.
It was an analogue broadcast, taped onto 6-head VHS, then recorded through an old video capture card (Asus V7700). Crappy I know, but I didn't have my digital capture card then and the DVDs weren't out.
I boosted the saturation with VirtualDub, but I didn't have any comparison footage so I didn't know exactly what to do with the settings. I'm also not very good with VirtualDub filters.
The other pictures are DVD screenshots.
